Cary McClennis (1789-1856) was a Scottish landowner who lived in Stirlingshire during the 19th century. Born in Tyndrum, the son of Guthrie McClennis, he inherited his family's farm in 1813. McClennis was a staunch Tory, viewing with jealousy and suspicion the transformation of Stirling into a fashionable railcar suburb for Glasgow merchants and seeing the development of heavy industries like coal mining, iron making, and brewing as threats to his family's traditional way of life. He died in 1856, leaving behind ten children, including Glen McClennis.
